论文摘要
通过设计越来越复杂的磁铁杂种杂种,可以强烈追求传统超导体中综合库珀对的生成和检测。在这里,我们从理论上证明了具有非零波数的镁质在相邻的常规超导体中普遍诱导围绕它们周围的综合三胞胎库珀对。所得的复合准粒子称为磁木龙,由磁体中的自旋翻转组成,该磁体由稀疏的超级流体冷凝物的云筛选。因此,它继承了一个较大的有效质量,可以通过实验测量。此外,我们证明了沉积在超导体上的两条磁力电线是由木酮的非本地和复合材料介导的可控镁定向耦合器。我们的分析预测了一个准颗粒,该准粒子能够在最简单的磁铁螺旋形异质结构中生成,控制和使用拼写的三胞胎库珀对。
Generation and detection of spinful Cooper pairs in conventional superconductors has been intensely pursued by designing increasingly complex magnet-superconductor hybrids. Here, we demonstrate theoretically that magnons with nonzero wavenumbers universally induce a cloud of spinful triplet Cooper pairs around them in an adjacent conventional superconductor. The resulting composite quasiparticle, termed magnon-cooparon, consists of a spin flip in the magnet screened by a cloud of the spinful superfluid condensate. Thus, it inherits a large effective mass, which can be measured experimentally. Furthermore, we demonstrate that two magnetic wires deposited on a superconductor serve as a controllable magnonic directional coupler mediated by the nonlocal and composite nature of magnon-cooparons. Our analysis predicts a quasiparticle that enables generation, control, and use of spinful triplet Cooper pairs in the simplest magnet-superconductor heterostructures.
